How to choose tungsten wire

Tungsten wire from Pride

As a product with no known substitute, tungsten goes far beyond the material used in light bulb filaments for more than a century. When you want to purchase tungsten wire, metal Cutting is more than just a product source - we are a resource providing knowledge and expertise. We have been a specialist in specialty tungsten products, including tungsten wires, since our establishment in 1967 and have been the exclusive North American distributor of Japanese tungsten and molybdenum products for over 30 years.

Characteristics and uses of tungsten wire

If you are looking to purchase tungsten wires for applications that require very high tensile strength, unique stiffness and no rebound, high melting point, low thermal expansion coefficient and low vapor pressure at high temperatures, then you are in luck: in wire form, our products retain many of tungsten's most valuable properties.

With excellent electrical and thermal conductivity, our tungsten products are widely used in glass-to-metal seals in lighting and electronic products, essential for the manufacture and testing of integrated circuits. Customers also purchase tungsten wires for medical device applications where electrical current is utilized and accuracy is critical. These include everything from electrocautery probes to sophisticated tools for stimulation and nerve detection, where the incredibly small diameter tungsten wire maintains its straightness and shape. The high tensile value makes our tungsten wires an economical and efficient alternative to precious metals for distal delivery and instrumentation in minimally invasive medical procedures. Its ultra-high density, comparable to that of precious metals, also makes the tungsten wire highly radiopaque, so it is good for fluorescent applications and can save a lot of money compared to precious metals.

Because our tungsten wire retains its shape at high temperatures, it is widely used in industrial furnaces as well as boron endoscopes for examining the interior of extremely high temperature environments, such as engines, turbines, pipes and tanks, which cannot be accessed by other means. Tungsten wire has very low vapor pressure at high temperature and is used in vacuum metallized coils used in surface coating of plastic toys, jewelry, cosmetic containers and small decorative parts.

Doped and undoped

When you want to buy tungsten wire, an important consideration is whether you want the product to be doped or undoped (pure). By virtue of its high recrystallization temperature, the doped tungsten wire maintains ductility at room temperature and very high operating temperatures and resists plastic deformation and breakage. The slender stacked structure of the doped wires also has good creep resistance and dimensional stability, and is slightly easier to work with than undoped wires. Our doped tungsten wire diameters range from 0.00025" (0.0065mm) and above.

We also supply undoped tungsten wires for applications where purity is critical; It is a greater than 99.99% pure product made from 99.999% pure powder. When you need to purchase tungsten wire at the highest possible purity, we are able to offer from mineral to finished product manufacturing in one place.

Buy tungsten wire from one source and can meet almost any need

In our most popular high performance engineering refractory POWDER metallurgy products, tungsten wires are available in a variety of diameters (≥0.00025"/ 0.0065mm); All doped and undoped compositions; Round silk and flat tape; And all surface finishes from wire drawing to various grades of electropolishing and even plating of 24-carat gold in various thicknesses. No matter what your application or needs are, you can turn to us for advice and the best solution.
